Users can search by photographer, title, collection, date, genre, geographic location and keywords. The results will be returned as galleries illustrated by thumbnail images with key data. Selections can then be expanded to show full records.

A little disconcerting at first, because the author does go off on other tangents besides photography. But his subtitle on his older blog: "a weblog about fine-art photography (and more)" does indicate you will get lots of other opinions about other topics. Most of the postings are URL links to other sites about something he feels is interesting, and often it is. This has become more of a webzine than blog over the last year.
